The Social Network: How People with Visual Impairment use Mobile Phones in Kibera, Kenya

Giulia Barbareschi, Catherine Holloway, Katherine Arnold, Grace Magomere, Wycliffe Ambeyi Wetende, Gabriel Ngare, Joyce Olenja

We present the findings of a case study of mobile technology use by People with Visual Impairment (VIPs) in Kibera, an informal settlement in Nairobi. We used contextual interviews, ethnographic observations and a co-design workshop to explore how VIPs use mobile phones in their daily lives, and how this use influences the social infrastructure of VIPs. Our findings suggest that mobile technology supports and shapes the creation of social infrastructure. However, this is only made possible through the existing support networks of the VIPs, which are mediated through four types of interaction: direct, supported, dependent and restricted.

Abstract

The Social Network: How People with Visual Impairment use Mobile Phones in Kibera, Kenya

Living in an informal settlement with a visual impairment can be very challenging resulting in social exclusion. Mobile phones have been shown to be hugely beneficial to people with sight loss in formal and high-income settings. However, little is known about whether these results hold true for people with visual impairment (VIPs) in informal settlements. We present the findings of a case study of mobile technology use by VIPs in Kibera, an informal settlement in Nairobi. We used contextual interviews, ethnographic observations and a co-design workshop to explore how VIPs use mobile phones in their daily lives, and how this use influences the social infrastructure of VIPs. Our findings suggest that mobile technology supports and shapes the creation of social infrastructure. However, this is only made possible through the existing support networks of the VIPs, which are mediated through four types of interaction: direct, supported, dependent and restricted.

80% of people with disabilities worldwide live in low resourced settings, rural areas, informal settlements and in multidimensional poverty. ICT4D leverages technological innovations to deliver programs for international development. But very few do so with a focus on and involving people with disabilities in low resource settings. Also, most studies largely focus on publishing the results of the research with a focus on the positive stories and not the learnings and recommendations regarding research processes.

Abstract

Disability design and innovation in computing research in low resource settings

80% of people with disabilities worldwide live in low resourced settings, rural areas, informal settlements and in multidimensional poverty. ICT4D leverages technological innovations to deliver programs for international development. But very few do so with a focus on and involving people with disabilities in low resource settings. Also, most studies largely focus on publishing the results of the research with a focus on the positive stories and not the learnings and recommendations regarding research processes. In short, researchers rarely examine what was challenging in the process of collaboration. We present reflections from the field across four studies. Our contributions are: (1) an overview of past work in computing with a focus on disability in low resource settings and (2) learnings and recommendations from four collaborative projects in Uganda, Jordan and Kenya over the last two years, that are relevant for future HCI studies in low resource settings with communities with disabilities. We do this through a lens of Disability Interaction and ICT4D.

Value beyond function: analyzing the perception of wheelchair innovations in Kenya

Barbareschi, G; Daymond, S; Honeywill, J; Singh, A; Noble, D; Mbugua, N; Harris, I; Austin, V; Holloway, C

The World Health Organization (WHO) defines Assistive Technology (AT) as “an umbrella term covering the systems and services related to the delivery of assistive products and services” [6]. This definition highlights how AT encompasses not only the physical and digital products used by millions of persons with disabilities (PWDs) worldwide, but also the systems and services that accompany the provision of these devices [78].

Abstract

Value beyond function: analyzing the perception of wheelchair innovations in Kenya

Innovations in the field of assistive technology are usually evaluated based on practical considerations related to their ability to perform certain functions. However, social and emotional aspects play a huge role in how people with disabilities interact with assistive products and services. Over a five months period, we tested an innovative wheelchair service provision model that leverages 3D printing and Computer Aided Design to provide bespoke wheelchairs in Kenya. The study involved eight expert wheelchair users and five healthcare professionals who routinely provide wheelchair services in their community. Results from the study show that both users and providers attributed great value to both the novel service delivery model and the wheelchairs produced as part of the study. The reasons for their appreciation went far beyond the practical considerations and were rooted in the fact that the service delivery model and the wheelchairs promoted core values of agency, empowerment and self-expression.

Inclusion and Independence: The impact of Mobile Technology on the Lives of Persons with Disabilities in Kenya and Bangladesh

Nusrat Jahan, Giulia Barbareschi, Clara Aranda Jan, Charles Musungu Mutuku, Naemur Rahman, Victoria Austin, Catherine Holloway

Worldwide it is estimated that there are over a billion people who live with some form of disability [1]. Approximately 80% of people with disabilities live in low-and-middle income countries (LMICs). The combination of an inaccessible environment compounded by socio-economic factors such as poverty and stigma, makes it more likely for people with disabilities to be marginalised and excluded from society [1]. Assistive Technologies (ATs) are known to bridge the accessibility gaps and allow for greater social inclusion. However, there is a lack of adequate access to ATs in LMICs, combined with often poorly designed services, which only magnifies these challenges, thus limiting the opportunities for persons with disabilities to live an independent life [2]. Despite the importance of AT, access to AT globally is inadequate with only 10 percent of those in need having access to the ATs that they need [2].

Abstract

Inclusion and Independence: The impact of Mobile Technology on the Lives of Persons with Disabilities in Kenya and Bangladesh

Globally, mobile technology plays a significant role connecting and supporting people with disabilities. However, there has been limited research focused on understanding the impact of mobile technology in the lives of persons with disabilities in low or middle- income countries. This paper presents the findings of a participatory photovoice study looking at the role that mobile phones play in the daily lives of 16 persons with disabilities in Kenya and Bangladesh. Participants used a combination of pictures and voice recordings to capture their own stories and illustrate the impact that mobile phone use has on their lives. Through thematic analysis, we categorized the benefits of mobile phones captured by participants as 1) Improved social connection; 2) Increased independence and 3) Access to opportunities. While mobile phones are ubiquitously used for communication, for persons with disabilities they become essential assistive technologies that bridge barriers to opportunities which are not accessible otherwise. Our paper adds evidence to the need for mobile phones for persons with disabilities to enable communication and connectivity in support of development.

A Preliminary Study to Understand How Mainstream Accessibility and Digital Assistive Technologies Reaches People in Lower- and Middle-Income Countries

End Superscript

Access to information on digital platforms not only facilitates education, employment, entertainment, social interaction but also facilitates critical governmental services, ecommerce, healthcare services and entrepreneurship [1]. Article 9 of United Nations Convention on the Rights of Persons with Disabilities (UNCRPD) enforces its signatories to commit to provide full accessibility to every citizen of the nation [2]. This has helped to spearhead accessibility directives such as the European Accessibility Act [3] that aims to improve the functioning of markets for accessible products and services. Such directives contribute to ensure that mainstream digital technologies (smartphones, computers etc.) are accessible for everyone and without being socially remarkable, they are able to assist in daily living. Additionally, there is evidence that improving access in mainstream technologies improves product experience and usability for everyone [4]. However, mainstream access has not been fully realized, leading to inferior opportunities for people with disabilities, a disparity which is more prominent in lower and middle-income countries [5].

Opportunities for Supporting Self-efficacy through Orientation and Mobility Training Technologies for Blind and Partially Sighted People

Maryam Bandukda, Catherine Holloway, Aneesha Singh, Giulia Barbareschi, Nadia Berthouze

We conducted semi-structured interviews with 20 BPS people and 8 Mobility and Orientation Trainers (MOT). The interviews were thematically analysed and organised into four overarching themes discussing factors influencing the self-efficacy belief of BPS people: Tools and Strategies for O&M training, Technology Use in O&M Training, Changing Personal and Social Circumstances, and Social Influences. We further highlight opportunities for combinations of multimodal technologies to increase access to and effectiveness of O&M training.

Abstract

Opportunities for Supporting Self-efficacy through Orientation and Mobility Training Technologies for Blind and Partially Sighted People

Orientation and mobility (O&M) training provides essential skills and techniques for safe and independent mobility for blind and partially sighted (BPS) people. The demand for O&M training is increasing as the number of people living with vision impairment increases. Despite the growing portfolio of HCI research on assistive technologies (AT), few studies have examined the experiences of BPS people during O&M training, including the use of technology to aid O&M training. To address this gap, we conducted semi-structured interviews with 20 BPS people and 8 Mobility and Orientation Trainers (MOT). The interviews were thematically analysed and organised into four overarching themes discussing factors influencing the self-efficacy belief of BPS people: Tools and Strategies for O&M training, Technology Use in O&M Training, Changing Personal and Social Circumstances, and Social Influences. We further highlight opportunities for combinations of multimodal technologies to increase access to and effectiveness of O&M training.

What difference does tech make? Conceptualizations of Disability and Assistive Technology among Kenyan Youth: Conceptualizations of Disability and AT

In this paper, we examine how young Kenyans without disabilities view people with disabilities and AT users. Findings show that while the portrayal of disability is often shaped by negative emotion, participants felt that many of the barriers affecting people with disabilities were created by society. Perceptions of AT differed –devices were not only seen as a mark of disability but also as a sign of access to resources. Therefore, what we see is an emergent picture where social barriers can be reinforced by poverty, and where poverty reinforces social barriers faced by people with disabilities. We conclude that access to appropriate technology alongside societal interventions tackling incorrect beliefs about disability can help to overcome the stigma faced by people with disabilities.

Abstract

What difference does tech make? Conceptualizations of Disability and Assistive Technology among Kenyan Youth: Conceptualizations of Disability and AT

Most research which investigates stigma towards with people with disabilities and the use of Assistive Technology (AT) are based in the Global North and focus on the experiences of people with disabilities and the consequences that stigma has on choices surrounding AT. However, stigma is a societal construct rooted in the attitude and beliefs that people without disabilities hold on disability and AT. Furthermore, the portrayal of people with disabilities and AT is dependent on the social context. In this paper, we examine how young Kenyans without disabilities view people with disabilities and AT users. Findings show that while the portrayal of disability is often shaped by negative emotion, participants felt that many of the barriers affecting people with disabilities were created by society. Perceptions of AT differed –devices were not only seen as a mark of disability but also as a sign of access to resources. Therefore, what we see is an emergent picture where social barriers can be reinforced by poverty, and where poverty reinforces social barriers faced by people with disabilities. We conclude that access to appropriate technology alongside societal interventions tackling incorrect beliefs about disability can help to overcome the stigma faced by people with disabilities.

Transforming a Monolithic Sheet of Nitinol into a Passive Reconfigurable Tactile Pixel Array Display at Braille Resolution

Tigmanshu Bhatnagar, Nicolai Marquardt, Mark Miodownik, Catherine Holloway

Shape changing materials create a unique opportunity to design reconfigurable tactile display actuators. In this paper, we present a method that transforms a single thin monolithic sheet of Nitinol into a passive reconfigurable tactile pixel array at Braille resolution. We have designed a 27x27 tactile pixel array in which each pixel can be selectively actuated with an external source of heat. The pixels rise 0.4mm vertically with a peak blocked force of 0.28kg and have an average blocked force of 0.23kg at room temperature. After cooling, the pixels can be mechanically reconfigured back to their flat state for repeatable actuation. We demonstrate this actuator’s interactive capabilities through a novel erasable tactile drawing interface.
